Produced Resources Main Growth Phase Secondary Metabolites Antibiotics

Secondary metabolites like antibiotics are produced after the main growth phase because they are made under stress when resources are limited and competition is high. This helps reduce competition by inhibiting other microorganisms.

Secondary metabolites like antibiotics are produced after the main growth phase because they are made under stress when resources are limited and competition is high. This helps reduce competition by inhibiting other microorganisms.

Front Suggest why secondary metabolites such as antibiotics are only produced after main growth phase of microorganism.
Back Secondary metabolites and growth:
  • In main growth phase, there is an excess of resources
  • Tend to be produced under stress - in stationary phase where resources are limiting population causing more competition
  • Antibiotics are produced to try and reduce competition for resources from bacteria so will only be produced when the resources are limited which is after main growth phase
